7.10.  COUT: Changing the output-relay function 
 

The output relay function of the Dräger RailGard is set during initial installation or re-
configuration of the unit. 
 
One of the following functions can be associated to the alarm relay: 
 
 

 

H or 

 

 

S or 

 

 

HM or 

 

 

SM 

 
where: 
 
 

 

H = with Hysteresis, non latching 

 

 

S = latching  

 

 

M = Monoflop (2-minute latching) 

 
The following diagram shows the logic for the various output functions and their 
switches.
